So Sunday morning around 8am I took a 20mg xr adderall to start studying for finals and I happened to have an extra 60mg vyvanse laying on the desk and without thinking about the risk i thought this would be a good idea to get even more work done. So the problem now is I haven't slept for over 41 hours and I don t feel anywhere near tired. I seriously feel like i have slept for a good 14 hours seconds ago. I've also only been able to eat two small meals. My vision also sometimes gets a little hazy and my body feels lighter and tingly as if i just took the medication almost euphoric like. This is my first time taking adderall and second time vyvanse. The good news is I have been able to get a lot of studying done.
